The CYCB1;1 promoter is activated in the G2-phase and the CYCB1;1:GUS protein is degraded at metaphase (M) (Colon-Carmona et al., 1999; Criqui et al., 2001). The elevated transcript levels of the S and G2 marker genes in 8-day-old leaves, the strong accumulations of CYCB1;1:GUS proteins in elo3 leaf primordia, and the decreased mitotic index in elo3 roots (Figure 3d,e,g) all suggested that Elongator mutations resulted in plant cells with the delayed entry into M-phase and an arrest at S- and/or G2-phase

Before reaching a balanced status of 4C- and 2C-cell numbers in the wild type, leaf primordia undergo vigorous cell proliferation, and the fractions of primordial cells usually consist of only 2C and 4C content that represent the G1- and G2-phases, respectively (Vlieghe et al., 2005; Takahashi et al., 2008 ... Hence, in the elo3 leaves, the delayed balance of 4C and 2C populations indicated that Elongator mutations resulted in a delayed progression from G1 to G2-phase

• Regulation of process

The HD-ZIPIII family genes are adaxially expressed in leaf primordia (McConnell et al., 2001). The microRNA miR165/166 is reported to repress the expression of the HD-ZIPIII family genes (Mallory et al., 2004). To investigate whether mutations of the WOX genes affect the pattern of HD-ZIPIII expression via the regulation of miR165/166, we analyzed the expression pattern of the 35Spro:miYFP-W line, in which miR165/166 function can be monitored by a reduction of YFP fluorescence (Toyokura et al., 2011 ...
